11.5.3.1.6

RXEDGIF Description

The RXEDGIF interrupt is set when an active edge (falling if RXPOL = 0, rising if RXPOL = 1) on the

RXD pin is detected. Clear RXEDGIF by writing a “1” to the SCIASR1 SCI alternative status register 1.

11.5.3.1.7

BERRIF Description

The BERRIF interrupt is set when a mismatch between the transmitted and the received data in a single

wire application like LIN was detected. Clear BERRIF by writing a “1” to the SCIASR1 SCI alternative

status register 1. This ﬂag is also cleared if the bit error detect feature is disabled.

11.5.3.1.8

BKDIF Description

The BKDIF interrupt is set when a break signal was received. Clear BKDIF by writing a “1” to the

SCIASR1 SCI alternative status register 1. This ﬂag is also cleared if break detect feature is disabled.

11.5.4

Recovery from Wait Mode

The SCI interrupt request can be used to bring the CPU out of wait mode.

11.5.5

Recovery from Stop Mode

An active edge on the receive input can be used to bring the CPU out of stop mode.
